Enhanced stainless steel ground rods

February 12, 2008 -- Harger Lightning & Grounding has introduced its stainless steel enhanced grounds rods (EGRs). According to Harger, the rods contain special salts that help lower soil resistivity and are used in conjunction with ground enhancement material such as Ultrafill. Ultrafill lowers the soil resistivity immediately around the ground rod, significantly improving its efficacy.

The Harger 300 Series stainless steel EGRs are highly resistant to corrosion; they are also used to overcome many of the problems caused by galvanic corrosion which can take place between dissimilar metals buried in close proximity such as copper clad ground grounds and guy anchors.

Other applications for the stainless steel EGR's include areas with acidic soils, airports, pipe lines, power plants and other industrial sites.

The company notes that the conductor portion of the ground rod is designed to help ensure the current has a downward path to ground, where other chemical ground rod manufacturers utilize a design which forces the electrical (lightning) current to go "up hill".

Another notable feature is an inspection cap on the top of the rod; this allows for inspection of the electrolytic salts. Harger says it will provide additional salts free of charge should the salts become depleted.

The EGRs are UL listed and are designed to last over 25 years, according to the company.
